ObjectiveTo summarize the best evidence for non-pharmacological intervention of delirium in adult patients in ICU, and evaluate the effect of its application.
MethodsAccording to the "6S" evidence pyramid model system, the literature was searched to obtain and summarize the best evidence of non-pharmacological interventions for delirium in adult ICU patients.There were 40 ICU nurses and 150 patients were recruited in a tertiary hospital in Wuhu, Anhui province by using the convenience sampling method.Based on the Joanna Briggs Institute(JBI)evidence-based health care model as the theoretical framework, through baseline audit, analysis of obstacles to the application of evidence, introduction of evidence, as well as re-audit of evidence after application, compare the incidence of delirium, the clinical outcome of patients and the level of knowledge of nurses on the prevention and management of delirium before and after the application of the best evidence.
ResultsFinally, 17 best evidences were included, including seven parts: risk factor identification and risk prediction, assessment and diagnosis, physical restraint, cognitive training, family participation, sleep management and early rehabilitation exercise.After the application of the best evidence, the incidence of delirium and unplanned extubation in ICU patients were significantly reduced, the length of hospitalization was significantly shortened (P < 0.05), and the duration of delirium was shortened (P < 0.01).The level of relevant knowledge of nursing staff was improved (P < 0.05).When the evidence was reviewed again after application, the implementation rate of each review standard was higher than the current review.
ConclusionsThe application of the best evidence for non-pharmacological intervention of delirium in adult patients in ICU has improved the delirium management process, which can prevent and reduce the incidence of delirium in patients, and improved clinical outcomes of patients.
